There are many updowns, tunnels, tight corners (even in the tunnnel) in 8km mountain road.

Take Route 121 from Yunishigawa Onsen to Kawaji Onsen. Ojika River is on the left, and Ikari Dam is ahead.

The view of the mountains and the valley is very pleasant.

Ojika River is on the left, and Ikari Dam is ahead. There is also a tunnel ahead, and if I go straight on, reach Kawaji Onsen, but this time, I will turn right and go through Kawaji Dam.

Look at this tunnel exit. It’s really dangerous. If I’m zoning out in a straight tunnel, I may fall into the lake.

Kawaji Dam 1st Tunnel is a very tight curved tunnel.

Kawaji 2nd Tunnel has a tight curve and groovings in the tunnel.

Hairpin corner where you can see the bottom of the cliff.

The scenery is very good and really fun to ride, but little scared in the first time.
